Fish community of Belocrkvan lakes

Abstract

Research of fish communities was carried out in November 2023 in artificial lakes in the area of Bela Crkva. Using a multiparameter probe, the basic physical and chemical parameters of water quality were measured, according to which the waters of these lakes belongs to the class I and II waters. In total, the presence of nine species from six families was registered. Of the total number of registered species, two are listed in the Berne Convention, while one species is listed in the Habitats Directive. According to national legislation, one species is strictly protected, while three species are protected. It can be concluded that the biological diversity of the ichthyofauna of the studied lakes is solid, and that the basic characteristic of the ichthyofauna is a high level of autochthonousness.

Istraživanja zajednica riba obavljena su u novembru 2023. godine u veštačkim jezerima na području Bele Crkve. Upotrebom multiparametarske sonde izmereni su i osnovni fizičko-hemijski parametri kvaliteta vode, prema kojima vode ovih jezera pripadaju vodama I i II klase. Registrovano je prisustvo devet vrsta iz šest familija, od kojih su dve navedene u Bernskoj konvenciji, dok je u Direktivi o staništima navedena jedna vrsta. Prema nacionalnom zakonodavstvu jedna vrsta je strogo zaštićena, dok je tri vrste zaštićeno. Može se zaključiti da je biološka raznovrsnost ihtiofaune ispitivanih jezera solidna, kao i da je osnovna karakteristika ihtiofaune visok nivo autohtonosti.
